4.2 Switch inputs (DI)
Unit operating modes and functions can be controlled
with switch (digital) inputs. All inputs are configurable to
any operation, and input polarity (NC/NO) can be select-
ed. The unit has two inputs (IO1 and IO2). SEC/SEM*
modules has three inputs more (IO3, IO4 and IO5).
Installation
Install switch devices to selected inputs (IO1-IO5) and
ground.
Settings
IO settings can be changed in
Settings
/
(1234)/IO controls
menu. Configure input type to
switch input
. Select ac-
tive state according to application. Closed selection will
active function when input is connected to ground (NO).
Operations
Select required switch function:
1. Emergency stop
Emergency stop when input active.
2. Stop
Unit stopped when input active.
3. Fireplace
Fireplace function activated by input pulse, function
time defined in Smart settings.
4. Hood
Cooker hood function active when input active.
5. Central vacuum (CVC)
Central vacuum cleaner function active when input
active.
6. Boost force
Boost mode active when input active, overrides
Away mode.
7. Away
Away mode active when input active.
8. Boost
Boost mode active when input active.
9. Modbus (not priority)
Input status can be read from Modbus.
10. Relay control (not priority)
Input status can control relay output.
11. Emergency stop resettable
Emergency stop activation. Emergency stop is reset
from user panel.
12. External alarm.
Alarm indication for external devices.

4.3 Voltage inputs (AI)
Unit operating modes can be controlled with analog
voltage (0...10V) and different sensors can be connected
to voltage inputs. The unit has two inputs (IO1 and IO2).
SEC/SEM* modules has three inputs more (IO3, IO4 and
IO5).
Installation
Install control or sensor cable to selected inputs (IO1-IO5)
and ground.
Settings
IO settings can be changed in
Settings
/
(1234)/IO controls
menu. Configure input type to
voltage input
.
Operations
Select required analog input function:
1. Operating mode
Operating mode control 0...10 VDC (+/- 0.5 V)
0 V = Control disabled
1 V = Travelling
2 V = Away
5 V = Home
8 V = Boost
10 V = Stopped
2. Operating mode, stepless
Operating mode control 0...10 VDC (+/- 0.5 V)
0 V = Control disabled
1 V = Travelling
2 V = Away
Stepless control between Away and Home
5 V = Home
Stepless control between Home and Boost
8 V = Boost
10 V = Stopped
3. Modbus AI
Analog voltage can be read from Modbus.
